So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Hlasta, Dennis J.; Luttinger, Daniel; Perrone, Mark H.; Silbernagel, Marla J.; Ward, Susan J.; Haubrich, Dean R. researched the compound: Ethyl indoline-2-carboxylate( cas:50501-07-0 ).Application In Synthesis of Ethyl indoline-2-carboxylate.They published the article 《α2-Adrenergic agonists/antagonists: the synthesis and structure-activity relationships of a series of indolin-2-yl and tetrahydroquinolin-2-yl imidazolines》 about this compound( cas:50501-07-0 ) in Journal of Medicinal Chemistry. Keywords: indolinylimidazoline preparation adrenergic agonist antagonist; quinolinylimidazoline preparation adrenergic agonist antagonist; structure activity adrenergic indolinylimidazoline. We’ll tell you more about this compound (cas:50501-07-0).

The synthesis and α2-adrenergic activity of a series of indolin-2-yl- and tetrahydroquinolin-2-ylimidazolines, e.g. I (R = Me, Et, allyl, Ph, CH2Ph, etc.; R1 = 5-F, 5-Cl, etc.) and II (R = H, Me) are described. The indolin-2-ylimidazoline I (R = Me, R1 = H) has potent α2-adrenergic agonist and antagonist activity. The modification of the substituents on the indoline ring of I led to the separation of these activities. Substitution on the aromatic ring of I with halogen or increasing the size of the N-alkyl substituent of I gave α2-adrenergic antagonists without agonist activity. The N-allylindoline I (R = allyl, R1 = H) is more potent than idazoxan in vitro and is equipotent in vivo, but is less receptor-selective (α2 vs. α1) than idazoxan. cis-1,3-Dimethylindolin-2-ylimidazoline is an α2-adrenergic agonist equal in potency to clonidine in vitro, whereas trans-1,3-dimethylindolin-2-ylimidazoline is a moderately potent α2-adrenergic antagonist.

Compounds were prepared with heterocyclic replacements for metabolically unstable esters of benzopyranyl indole-2-carboxylic esters, which showed good in vitro and in vivo cardioprotective efficacies possibly through the opening of mitochondrial ATP-sensitive potassium channel (KATP). Initially, indolin-2-yl-heterocycles were constructed using unprotected indoline-2-carboxylic acid, but the cyclization was proceeded with oxidation of the indoline ring to the indole, which did not react with benzopyranyl epoxide. An N-BOC group was introduced to deplete the electron d. of the indoline ring. Various indolin-2-yl-heterocycles, such as I and II, were prepared by the cyclization of the building blocks including carboxamide, β-hydroxy amide, hydrazide, nitrile starting from N-BOC-indoline-2-carboxylic acid.
